What is known of the Cathars largely comes in what is preserved by the critics in the Catholic Church which later destroyed them in the Albigensian Crusade. Alain de Lille, , accused the Cathars of believing in two gods, one of light and one of darkness. Durand de Huesca, responding to a Cathar tract indicates that they regarded the physical world as the creation of Satan. A former Italian Cathar turned Dominican, Sacchoni in 1250 testified to the Inquisition that his former co-religionists believed that the devil made the world and everything in it. Catharism probably roots in Bogomilism, founded by Theophilos in the 10th century, who in turn owed many ideas to the earlier Paulicians in Armenia and the Near East and had strong impact on the history of the Balkans. Their true origin probably lies within earlier sects such as Nestorianism, Marcionism and Borboritism, who all share the notion of a docetic Jesus. Like these earlier movements, Bogomilites agree upon a dualism between body and soul, matter and spirit, and a struggle between good and evil. Rejecting most of the Old Testament, they opposed the established Catholic Church whose deity they considered to be the devil. Among the Cathars, there have been both an absolute dualism (shared with Bogomilites and early Christian Gnosticism) and mitigated dualism as part of their own interpretation. Mitigated dualists are closer to Christianity, regarding Lucifer as an angel created (through emanation, since by rejecting the Old Testament, they rejected creation ex nihilo) by God, with Lucifer falling because of his own will. On the other hand, absolute dualists regard Lucifer as the eternal principle of evil, not part of God's creation. Lucifer forced the good souls into bodily shape, and imprisoned them in his kingdom. Following the absolute dualism, neither the souls of the heavenly realm nor the devil and his demons have free will but merely follow their nature, thus rejecting the Christian notion of sin. The Catholic church reacted to spreading dualism in the Fourth Council of the Lateran (1215), by affirming that God created everything from nothing; that the devil and his demons were created good, but turned evil by their own will; that humans yielded to the devil's temptations, thus falling into sin; and that, after Resurrection, evil people will suffer along with the devil, while good people enjoy eternity with Christ.
